The Week in Mac Accessories: Portable power

This week’s roundup of new accessories for the Mac include ways to make sure you have all the power and protection you need.

The $60 Tamakwa Sleeve for MacBook Air 13″ is lined with wool, has a helpful pull-strap to cinch it closed, and—this is true—will completely compost in six months if you bury it in your backyard. Just make sure you’ve taken out your MacBook Air first.

This accessory maker has introduced its Cabana line of tech protection, ranging from a $40 MacBook Air sleeve to the $100 Sonic Backpack, each designed to let you carry and protect your Apple gear in nautical style.

We got a gander at the $60 iCalc Bluetooth Calculator Keypad at Macworld/iWorld. The keypad-slash-calculator is designed to attach to the end of Apple’s Bluetooth Wireless Keyboard, serving double duty as a standalone calculator and a Bluetooth numeric keypad.

Need a slot-loading optical drive to burn DVDs and Blue-Rays from your Mac? The $150 MCE Fovea Extreme is a Blu-Ray drive and burner that connects to your Mac via USB. The $50 MCE Fovea 8X SuperDrive is a DVD and CD Recordable USB drive.

This company’s new line of HOBO UX100 Data Loggers are Mac-based products ranging from $75 to to $189. They let you measure temperature and humidity inside and outside of the house from the comfort of your Mac—wherever it may reside.

The $999 Solar Juicz provides 62 watts of solar power to MacBook Pros and Airs, and it folds up for easy storage and transport. It’s also powerful: Quickertek’s previous top model could generate only 55 watts.

The $50 Coccoon is a polycarbonite case for the 15-inch MacBook pro with Retina display. It comes in four colors and has polished edges.

The $45 PlugBug World lets you charge your MacBook and an iOS device from a single outlet, at the same time. The new World version includes five different adapters, including those that will let you use the device to power your electronics in Europe.
